Question

一家快餐连锁店春季卖出 $4.5$ 百万个汉堡，夏季卖出 $5$ 百万个，秋季卖出 $4$ 百万个；冬季销量未知。如果这家连锁店全年汉堡销量中正好有 $25\%$ 是秋季卖出的，那么冬季卖出多少百万个汉堡？

A fast food chain sold $4.5$ million hamburgers in the spring, $5$ million in the summer, and $4$ million in the fall; the number sold in the winter is unknown. If exactly $25\%$ of the chain's hamburgers are sold in the fall, how many million hamburgers are sold in the winter?

$2.5$

$3$

$3.5$

$4$

$4.5$

答案：A

知识点：百分数

难度评级：960

解答：

如果秋季 $4$ 百万个是全年总量的 $25\%$ ，那么全年总量是 $16$ 百万个。

冬季销量是 $16 - (4.5 + 5 + 4) = 2.5$ 百万个。

所以正确答案是 A。

If the fall sales of $4$ million are $25\%$ of the yearly total, then the yearly total is $16$ million.

The winter sales are $16 - (4.5 + 5 + 4) = 2.5$ million.

Thus, the correct answer is A .
